Thanks Luca,
configuring
board_ref_clock = WL12XX_REFCLOCK_38, /* 38.4 MHz */
gave me the possibility to scan network but only for an essid on channel1 (delivered from one AP).
I couldn't scan others essids on other channels (for example channel 6) and I don't know why.
Have you got any idea about it ?
Regards
Alberto

Even if you can't use it in real life, it could be worth trying a newer kernel if you keep getting problems with that old one. You could also try compat-wireless to get a newer wireless subsystem, at least.

Yes, that's the value I'm talking about. You should put it in your boardfile, something like this (from panda):
static struct wl12xx_platform_data omap_panda_wlan_data __initdata = {
.board_ref_clock = WL12XX_REFCLOCK_38, /* 38.4 MHz */ };
You can find these values in the include/linux/wl12xx.h file.
